Times Square's "zipper," which told New York toilers and tourists of the bombing of Pearl Harbor, V-J Day, the assassination of President John F. Kennedy and other world-shaking events since 1928, is back in business.

The famous 369-foot illuminated moving word sign wrapped around the building at One Times Square was shut down two months ago to install modern lighting technology and make its news reports more readable during daylight hours.The landmark at the center of the city's entertainment district was originally begun by The New York Times but is now operated by Dow Jones & Co., providing its own news along with information from ESPN SportsTicker and the Associated Press.

The sign, which used incandescent bulbs to flash the headlines of the day, now uses 235,000 amber light diodes to keep passers-by informed of the latest developments.
